摘要： An object of the present invention is to obtain a brake system that can generate appropriate braking force without influence of temperature. A brake system includes: a piston that presses pressing members; a motor that moves the piston; a current detection unit that detects current flowing in the motor; a storage unit that stores a correspondence relation between idle running current and motor stopping current; a motor stopping current setting unit that sets the motor stopping current using the storage unit and the idle running current; and a control unit that stops to supply the current to the motor when the current flowing in the motor reaches the motor stopping current. The correspondence relation is set so that the rate of change of the motor stopping current relative to the idle running current becomes smaller when the idle running current is small than that when it is large.

摘要： A parking brake actuator generates and applies a braking force to a vehicle wheel by converting a rotation movement of a screw member which is rotated by an electric parking brake driving device into a translatory movement and transmitting the converted translatory movement to a piston to push a brake pad to a disc by the piston. The electric parking brake driving device includes an electric motor and a reduction gear mechanism which transmits the driving force of the electric motor to the electric parking brake driving device. The reduction gear mechanism includes a pinion gear fixed to an output shaft of the electric motor, a first gear shaft rotatably supported on a first bearing member provided on a gear body and a first wheel gear formed on the first gear shaft and engaging the first wheel gear to thereby reduce the speed of driving force of the electric motor.

摘要： An electric parking brake includes an actuator, first and second linings adjacent respectively to first and second end surfaces of a brake disk, and first and second braking members. Through operation of the actuator, the first lining is driven by the first braking member to move toward or away from the first end surface in a direction to thereby move the second braking member toward or away from the second end surface in an opposite direction, so that the first and second linings can be moved toward each other to clamp the brake dish therebetween.

摘要： A retaining formation defined on a brake lever of an air disc brake includes a push fit/snap fit connection for releasably securing a push rod to a brake lever. The retaining formation can include a pinned connection and a ball and socket joint, and a main axis of the pinned connection is coincident with a center of rotation of the ball and socket joint. The retaining formation can include a concave formation on one of the push rod and the brake lever and a corresponding convex formation on the other of the push rod and the brake lever. The concave formation at least partially surrounds the convex formation to prevent axial separation of the push rod and the brake lever. A method of assembling a brake subassembly includes the steps of assembling a push rod and a brake lever including a retaining formation such that at least a portion of the retaining formation deforms during assembly and resiles when the push rod is assembled to the brake lever to provide a snap fit connection therebetween. Another method of manufacturing a retaining formation includes the steps of providing one of a push rod and a brake lever with a concave formation, providing the other of the push rod and the brake lever with a convex formation able to receive the concave formation, assembling the concave formation and the convex formation, mechanically working the one of the push rod and the brake lever with the concave formation such that the concave formation at least partially surrounds the convex formation to prevent axial separation of the push rod and the brake lever.
